DETAILED DESCRIPTION

External Appearance of Electronic Apparatus

FIGS. 1 and 2 are respectively a front side view and a rear side viewillustrating an external appearance of an electronic apparatus 1. Theelectronic apparatus 1 may be a mobile phone such as a smart phone, andcan communicate with another communication device via a base station, aserver, and the like. As illustrated in the example in FIGS. 1 and 2,the electronic apparatus 1 has a plate-like shape that is substantiallyrectangular in a plan view. As illustrated in FIGS. 1 and 2, the outerplate (surface) of the electronic apparatus 1 includes a cover panel 2and a casing 3.

The cover panel 2 has a plate-like shape and an approximatelyrectangular shape in a plan view. The cover panel 2 constitutes aportion other than an edge area in the front surface of the electronicapparatus 1 as illustrated in FIG. 1. The cover panel 2 includes a firstsurface 70 that constitutes a portion of the front surface of theelectronic apparatus 1 and a second surface 71 that is positioned on theopposite side to the first surface 70 (see FIG. 9 described below).Hereinafter, the first surface 70 is referred to as an “outer surface70” and the second surface 71 is referred to as an “inner surface 71.”

The cover panel 2 is made of, for example, sapphire. That is, the coverpanel 2 is a panel of a one-layer structure having a layer made ofsapphire which is disposed on the surface of the electronic apparatus 1.Here, sapphire refers to a single crystal containing alumina(Al.sub.2O.sub.3) as a main component, and a single crystal whose purityof Al.sub.2O.sub.3 is approximately greater than or equal to 90% in thepresent specification. The purity of Al.sub.2O.sub.3 is preferablygreater than or equal to 99% which provides a resistance to damage tothe cover panel and a reduction of cracks or chipping.

In an example embodiment, the cover panel 2 is a panel of a one-layerstructure having a layer made of sapphire which is disposed on thesurface of the electronic apparatus 1. However, the cover panel 2 may bea composite panel (laminated panel) of a multilayer structure havingsuch a layer. For example, the cover panel 2 may be a composite panel ofa two-layered structure configured of a first layer (sapphire panel)made of sapphire which is disposed on the surface of the electronicapparatus 1 and a second layer (glass panel) made of glass which isattached to the first layer. In addition, the cover panel 2 may be acomposite panel of a three-layered structure configured of a layer(sapphire panel) made of sapphire which is disposed on the surface ofthe electronic apparatus 1, a layer (glass panel) made of glass which isattached to the layer made of sapphire, and a layer (sapphire panel)made of sapphire which is attached to the layer made of glass. Further,the cover panel 2 may include a layer made of crystalline materialsother than sapphire such as diamond, zirconia, titania, crystal, lithiumtantalate, and aluminum oxynitride.

The cover panel 2 includes a display area 2 a and an edge area 2 b, forexample a peripheral edge. Various pieces of information such ascharacters, symbols, figures, and moving images displayed by a displaydevice 16, as described below with reference, for example, to FIG. 3,are visually recognized by a user through the display area 2 a in thecover panel 2. The edge area 2 b in the cover panel 2 that surrounds thedisplay area 2 a may be black because of, for example, a film beingattached thereto. Accordingly, the display by the display device 16 isdifficult to be visually recognized by the user through the edge area 2b.

A front imaging unit 4 is disposed on the upper end of the cover panel2. The touch panel 17 described below with reference, for example, toFIG. 3, is attached to the inner surface 71 of the cover panel 2. Theuser can provide various instructions with respect to the electronicapparatus 1 by operating the display area 2 a of the cover panel 2 usinga finger or the like.

The casing 3 includes the edge area of the front surface, the sidesurface, and the rear surface of the electronic apparatus 1. The casing3 is made of, for example, a resin. Operation keys 5 a, 5 b, and 5 c anda microphone hole 6 are provided in the edge area of the front surfaceof the electronic apparatus 1 in the casing 3. In the electronicapparatus 1 illustrated in FIG. 1, the operation keys 5 a to 5 c arehardware keys, but the respective operation keys 5 a to 5 c may besoftware keys displayed on the display area 2 a. The microphone hole 6may be provided in a portion other than the cover panel 2, for example,on the casing 3 as described above. For example, the microphone hole 6may be provided on the side surface or the rear surface of the casing 3so as not to pick up the operation sound when the display area 2 a isoperated by the user during communication on the phone.

A side key 7 which activates the electronic apparatus 1 is provided onthe side surface of the electronic apparatus 1. In addition, a rearimaging unit 8 including an imaging device 8 a and a lighting device 8b, and speaker holes 9 are provided on the rear surface of theelectronic apparatus 1 as illustrated in FIG. 2. The lighting device 8 bis, for example, a light-emitting diode (LED) that plays a role of aflash emitting light while performing imaging with the imaging device 8a.

Electrical Configuration of Electronic Apparatus

FIG. 3 is a block diagram illustrating the electrical configuration ofthe electronic apparatus 1. As illustrated in FIG. 3, the electronicapparatus 1 includes the control unit 10, a wireless communication unit14, the display device 16, the touch panel 17, the operation keys 5 a to5 c, the side key 7, a microphone 18, the piezoelectric vibratingelement 19, a speaker 20, the front imaging unit 4, the rear imagingunit 8, and a battery 21. These elements which are provided in theelectronic apparatus 1 are accommodated in the casing 3 of theelectronic apparatus 1.

The control unit 10 includes a Central Processing Unit (CPU) 11, aDigital Signal Processor (DSP) 12, and a storage unit 13. The controlunit 10 manages the overall operation of the electronic apparatus 1 bycontrolling other elements of the electronic apparatus 1. The storageunit 13 is, for example, a ROM (Read Only Memory) and a RAM (RandomAccess Memory). Main programs, a plurality of application programs, andthe like which are control programs for controlling the electronicapparatus 1, specifically, for controlling respective elements such asthe wireless communication unit 14, the display device 16, and the likeincluded in the electronic apparatus 1, are stored in the storage unit13. Various functions of the control unit 10 can be realized by the CPU11 and the DSP 12 executing various programs in the storage unit 13.

The wireless communication unit 14 includes an antenna 15. The wirelesscommunication unit 14 receives or transmits a communication signalfrom/to a mobile phone different from the electronic apparatus 1, and/orto a communication device such as a web server connected to the Internetusing an antenna 15 via a base station or the like.

The display device 16 is, for example, a liquid crystal display or anorganic electroluminescence (EL) display. As described above, variouspieces of information displayed on the display device 16 are visuallyrecognized from the outside of the electronic apparatus 1 through thedisplay area 2 a.

The touch panel 17 is, for example, a projection type electrostaticcapacitance touch panel. The touch panel 17 is attached to the innersurface 71 of the cover panel 2. The touch panel 17 includes twosheet-like electrode sensors which are disposed so as to face eachother. When the user touches the display area 2 a using such as a fingeror the like, the electrostatic capacitance of the portion facing theoperator in the touch panel 17 is changed. The touch panel 17 outputs anelectrical signal according to the change of the electrostaticcapacitance to the control unit 10. In this manner, the touch panel 17can detect contact with respect to the display area 2 a of the operator.

The operation keys 5 a to 5 c and the side key 7 output an electricalinstruction signal to the control unit 10 when pressed. A voice or thelike of the user is input to the microphone 18 during communication onthe phone and the input voice or the like is converted to an electricalsignal that is output to the control unit 10.

The piezoelectric vibrating element 19 is attached to the inner surface71 of the cover panel 2. The piezoelectric vibrating element 19 isvibrated by a driving voltage applied from the control unit 10. Thecontrol unit 10 generates a driving voltage based on a sound signal andprovides the driving voltage to the piezoelectric vibrating element 19.The cover panel 2 is vibrated by the piezoelectric vibrating element 19which vibrates based on the driving voltage from the control unit 10. Asa result, a reception sound is transmitted to the user from the coverpanel 2. The volume of the reception sound is set to a degree such thatthe user can appropriately hear the sound when the cover panel 2 is putclose to an ear of the user. Details of the piezoelectric vibratingelement 19, and the reception sound transmitted to the user from thecover panel 2, are described below.

In the description below, a case in which the reception sound istransmitted to the user from the cover panel 2 by the piezoelectricvibrating element 19 is described, but a dynamic speaker that convertsthe electric sound signal from the control unit 10 into a sound and thenoutputs the sound may be adopted instead of the piezoelectric vibratingelement 19. Receiver holes are provided in the cover panel 2 or thecasing 3 when a dynamic speaker is used. The sound output from thedynamic speaker is output to the outside from the receiver holesprovided on the cover panel 2 or the casing 3. The volume of the soundoutput from the receiver holes is set to be smaller than that of thesound output from the speaker holes 9.

The speaker 20 provides a reception signal or the like to the user whois present at a location separated from the electronic apparatus 1 byconverting the electrical sound signal input from the control unit 10into a sound and then outputting the sound. The front imaging unit 4 andthe rear imaging unit 8 capture still images and moving images. Thebattery 21 outputs a power source for use by the electronic apparatus 1.The power output from the battery 21 is supplied to respectiveelectronic components contained in the control unit 10 or the wirelesscommunication unit 14 included in the electronic apparatus 1.

Details of Piezoelectric Vibrating Element

FIGS. 4 and 5 illustrate a top view and a side view, respectively, of astructure of the piezoelectric vibrating element 19. As illustrated inFIGS. 4 and 5, the piezoelectric vibrating element 19 has a long shapein one direction. Specifically, the piezoelectric vibrating element 19has a long and narrow rectangular plate shape in a plan view. Thepiezoelectric vibrating element 19 has, for example, a bimorphstructure. The piezoelectric vibrating element 19 includes a firstpiezoelectric ceramic plate 19 a and a second piezoelectric ceramicplate 19 b which are bonded to each other through a shim material 19 c.

The configuration of the piezoelectric vibrating element is not limitedto the specific example described above. For example, a piezoelectricvibrating element in which a piezoelectric plate is configured oforganic piezoelectric materials such as polyvinylidene fluoride andpolylactic acid may be used.

In the piezoelectric vibrating element 19, when a positive voltage isapplied to the first piezoelectric ceramic plate 19 a and a negativevoltage is applied to the second piezoelectric ceramic plate 19 b, thefirst piezoelectric ceramic plate 19 a extends along the longitudinaldirection and the second piezoelectric ceramic plate 19 b contractsalong the longitudinal direction. Accordingly, as illustrated in FIG. 6,the piezoelectric vibrating element 19 is bent into a convex shape withthe first piezoelectric ceramic plate 19 a being outside.

In contrast, in the piezoelectric vibrating element 19, when a negativevoltage is applied to the first piezoelectric ceramic plate 19 a and apositive voltage is applied to the second piezoelectric ceramic plate 19b, the first piezoelectric ceramic plate 19 a contracts along thelongitudinal direction, and the second piezoelectric ceramic plate 19 bextends along the longitudinal direction. Accordingly, as illustrated inFIG. 7, the piezoelectric vibrating element 19 is bent into a convexshape with the second piezoelectric ceramic plate 19 b being outside.

The piezoelectric vibrating element 19 flexurally vibrates byalternatively taking on the state of FIG. 6 and the state of FIG. 7. Thecontrol unit 10 allows the piezoelectric vibrating element 19 toflexurally vibrate by applying an alternating current (AC) voltagebetween the first piezoelectric ceramic plate 19 a and the secondpiezoelectric ceramic plate 19 b.

Only one structure configured of the first piezoelectric ceramic plate19 a and the second piezoelectric ceramic plate 19 b, which are bondedto each other by interposing the shim material 19 c therebetween, isprovided in the piezoelectric vibrating element 19 illustrated in FIGS.4 to 7. However, a plurality of the structures may be laminated to eachother. For example, 28 or more layers that are laminated provide anincreased level of vibration that can be transmitted to the cover panel2. Accordingly, 44 or more layers that are laminated provide anincreased sufficiency in the vibration that can be transmitted to thecover panel 2.

The piezoelectric vibrating element 19 having such a structure isdisposed on the edge area of the inner surface 71 of the cover panel 2.Specifically, the piezoelectric vibrating element 19 is disposed in acentral portion in a short-length direction (lateral direction) in theupper end of the inner surface 71 of the cover panel 2. The longitudinaldirection of the piezoelectric vibrating element 19 is arranged alongthe short-length direction of the cover panel 2. In this manner, thepiezoelectric vibrating element 19 flexurally vibrates along theshort-length direction of the cover panel 2. Further, the center in thelongitudinal direction of the piezoelectric vibrating element 19corresponds to the center in the short-length direction of the upper endof the inner surface 71 of the cover panel 2.

Here, as illustrated in FIGS. 6 and 7, the center in the longitudinaldirection of the piezoelectric vibrating element 19 flexurally vibratinghas the largest displacement amount. Accordingly, an area whosedisplacement, at a time of flexural vibration, is the largest in thepiezoelectric vibrating element 19 corresponds to the center in theshort-length direction of the upper end of the inner surface 71 of thecover panel 2 since the center in the longitudinal direction of thepiezoelectric vibrating element 19 corresponds to the center in theshort-length direction of the upper end of the inner surface 71 of thecover panel 2.

Regarding Generation of Reception Sound

In the electronic apparatus 1, an air conduction sound and a conductionsound are transmitted to the user by the piezoelectric vibrating element19 through the cover panel 2 which is vibrated by the piezoelectricvibrating element 19. That is, the vibration of the piezoelectricvibrating element 19 is transmitted to the cover panel 2 so that the airconduction sound and the conduction sound are transmitted to the userfrom the cover panel 2.

Here, the term “air conduction sound” means a sound recognized in ahuman brain by the vibration of an eardrum due to a sound wave (airvibration) which enters an external auditory meatus hole (a so-called“ear hole”). On the other hand, the term “conduction sound” is a soundrecognized in a human brain by the vibration of the eardrum due to thevibration of an auricle transmitted to the eardrum. Hereinafter, the airconduction sound and the conduction sound will be described in detail.

FIG. 8 is a view for describing the air conduction sound and theconduction sound. FIG. 8 illustrates a structure of an ear of the userof the electronic apparatus 1. In FIG. 8, a dotted line 400 indicates aconduction path of a sound signal (sound information) of the airconduction sound. A solid line 410 indicates the conduction path of thesound signal of the conduction sound.

When the piezoelectric vibrating element 19 mounted on the cover panel 2vibrates based on the electric sound signal indicating the receptionsound, the cover panel 2 vibrates, and a sound wave is output from thecover panel 2. When the user moves the cover panel 2 of the electronicapparatus 1 close to an auricle 300 of the user by holding theelectronic apparatus 1 in a hand, or the cover panel 2 of the electronicapparatus 1 is set to (brought into contact with) the auricle 300 of theuser, the sound wave output from the cover panel 2 enters an externalauditory meatus hole 310. The sound wave from the cover panel 2 entersin the external auditory meatus hole 310 and the eardrum 320, and theeardrum 320 vibrates. The vibration of the eardrum 320 is transmitted toan auditory ossicle 330 and the auditory ossicle 330 vibrates. Inaddition, the vibration of the auditory ossicle 330 is transmitted to acochlea 340 and is converted into an electrical signal in the cochlea340. The electrical signal is transmitted to the brain by passingthrough an acoustic nerve 350 and the reception sound is recognized inthe brain. In this manner, the air conduction sound is transmitted fromthe cover panel 2 to the user.

Further, when the user puts the cover panel 2 of the electronicapparatus 1 to the auricle 300 of the user by holding the electronicapparatus 1 in a hand, the auricle 300 is vibrated by the cover panel 2,which cover panel 2 is vibrated by the piezoelectric vibrating element19. The vibration of the auricle 300 is transmitted to the eardrum 320,and thus the eardrum 320 vibrates. The vibration of the eardrum 320 istransmitted to the auditory ossicle 330, and thus the auditory ossicle330 vibrates. The vibration of the auditory ossicle 330 is transmittedto the cochlea 340 and is converted into an electrical signal in thecochlea 340. The electrical signal is transmitted to the brain bypassing through the acoustic nerve 350 and the reception sound isrecognized in the brain. In this manner, the conduction sound istransmitted from the cover panel 2 to the user. FIG. 8 illustrates anauricular cartilage 300 a in the inside of the auricle 300.

Bone conduction sound is a sound recognized in a human brain by thevibration of the skull and direct stimulation of the inner ear such asthe cochlea caused by the vibration of the skull. In FIG. 8, in a caseof vibrating the jawbone 500, the transmission path of the sound signalwhile the bone conduction sound is recognized in the brain is indicatedwith a plurality of arcs 420.

As described above, the air conduction sound and the conduction soundcan be transmitted from the cover panel 2 to the user of the electronicapparatus 1 due to the vibration of the cover panel 2 through thevibration of the piezoelectric vibrating element 19. The user can hearthe air conduction sound from the cover panel 2 by moving the coverpanel 2 close to an ear (auricle). Further, the user can hear the airconduction sound and the conduction sound from the cover panel 2 bybringing the cover panel 2 into contact with an ear (auricle).

Since the user can hear a sound when the user puts the cover panel 2 toan ear, communication using the electronic apparatus 1 can be performedwithout much concern regarding the position of the electronic apparatus1 with respect to the ear.

In addition, since the user can hear the conduction sound due to thevibration of the auricle, it is easy for the user to hear the sound evenwhen there is a large amount of ambient noise. Accordingly, the user canappropriately perform communication even when there is a large amount ofthe ambient noise.

In addition, even in a state in which earplugs or earphones are fixed tothe ears of the user, the reception sound from the electronic apparatus1 can be recognized by setting the cover panel 2 to the auricle.Further, even in the state in which headphones are fixed to the ears ofthe user, the reception sound from the electronic apparatus 1 can berecognized by putting the cover panel 2 to the headphones.

The sound from the cover panel 2 becomes easy to hear when the usermoves the upper end of the cover panel 2 (particularly, the centralportion of the upper end in the short-length direction DR2 whichcorresponds to the placement of the piezoelectric vibrating element 19)close to an ear, or puts the upper end thereof to an ear.

First Example Embodiment Cross-Sectional View of Electronic Apparatus

The configuration of an electronic apparatus 1 in which a cover panel 2has resistance to breakage is described below. FIG. 9 is across-sectional view of the electronic apparatus 1 according to a firstexample embodiment. FIG. 9 is a cross-sectional view of the electronicapparatus 1 taken along a line A-A illustrated in FIGS. 1 and 2. FIG. 10is an exploded perspective view of the electronic apparatus 1 accordingto the first example embodiment. In addition, in FIG. 10, somecomponents, such as a plurality of cables (wirings) 25 (see FIG. 9)electrically connecting a plurality of electronic components to oneanother and the touch panel 17 included in the electronic apparatus 1,are omitted for avoiding complexity in the drawing.

As illustrated in FIGS. 9 and 10, a casing 3 of the electronic apparatus1 in the present embodiment includes a front casing 3 a and a backcasing 3 b. The front casing 3 a and the back casing 3 b are connected(fixed) to each other using a claw or the like, or are fixed to eachother through fastening a screw or the like. A cover panel 2 is attachedto the front casing 3 a. An area attached to the front casing 3 a(casing 3) in the cover panel 2 is referred to herein as a “first area40”.

FIG. 11 is a view illustrating a cover panel 2 of the first example. InFIG. 11, the first area 40 is indicated by left-upward oblique lines. Asillustrated in FIG. 11, the first area 40 is an edge area of the coverpanel 2. In addition, as illustrated in FIG. 9, the first area 40 hasresistance to deformation and breakage even when a load is applied fromthe outside because the first area 40 is supported by the front casing 3a. As shown in FIGS. 9, 10 and 11, casing 3 includes the front casing 3a and the back casing 3 b. However, the casing 3 may be configured ofonly one member or a combination of three or more members.

As illustrated in FIGS. 9 and 10, the touch panel 17 and thepiezoelectric vibrating element 19 are attached to the inner surface 71of the cover panel 2 using a double-sided tape or an adhesive. Thedisplay device 16 is disposed so as to face the cover panel 2 and thetouch panel 17 (more specifically, the cover panel 2 to which the touchpanel 17 is attached). An area in the cover panel 2 facing the displaydevice 16 is referred to as a “second area 41.” As illustrated in FIG.11, the second area 41 is positioned further inside the cover panel thanthe first area 40 in the cover panel 2. In FIG. 11, the second area 41is indicated by right-upward oblique lines.

Referring again to FIGS. 9 and 10, a plate-like component 26 is disposedso as to face the cover panel 2 on the rear surface of the displaydevice 16. The plate-like component 26 is provided to reduce deformationand cracks of the cover panel 2 due to a possible load applied to thecover panel 2 from the outside. The plate-like component 26 is made of ametal material such as SUS (Steel Use Stainless). The second area 41faces a portion of the plate-like component 26. In addition, the secondarea 41 is supported by components (in the example of FIG. 9, the touchpanel 17, the display device 16, the plate-like component 26, a printedboard 27, and the battery 21) in the casing 3 of the electronicapparatus 1. The second area 41 has resistance to deformation andbreakage due to rigidity or the like of the components in the casing 3even when the load is applied from the outside. Since the cover panel 2and the components in the casing 3 are supported by the plate-likecomponent 26, even when the second area 41 is deformed, an amount ofdeformation in the second area 41 becomes small such that the secondarea 41 becomes resistant to breakage. For reinforcement, a concaveportion extending along the short-length direction or the longitudinaldirection of the electronic apparatus may be provided in the plate-likecomponent 26.

In the first example, as illustrated in FIG. 10, the front casing 3 a(casing 3) and the plate-like component 26 are formed integrally. Morespecifically, the plate-like component 26 formed by insert molding isdisposed on the inner surface of the front casing 3 a. However, theplate-like component 26 and the front casing 3 a (casing 3), forexample, may be formed separately and the plate-like component 26 may befixed to the front casing 3 a. The plate-like component 26 may be fixedto the casing 3 through a component fixed to the casing 3. An opening 44is provided on the plate-like component 26. The plate-like component 26includes a first surface 60 facing the cover panel 2 and a secondsurface 61 positioned on the opposite side to the first surface 60.

Referring again to FIGS. 9 and 10, the printed board 27, to whichvarious components such as the CPU 11 and the DSP 12 are mounted, isdisposed so as to face the second surface 61 of the plate-like component26. The printed board 27 is electrically connected to an electroniccomponent included in the electronic apparatus 1 by the cable 25. In theexample of FIG. 9, the printed board 27 is connected with the touchpanel 17, the display device 16, the piezoelectric vibrating element 19,and the rear imaging unit 8 by four cables 25. The battery 21 isinstalled such that the battery 21 faces the surface positioned on theopposite side to the surface on the plate-like component 26 side in theprinted board 27.

A holder 28, which is provided in the casing 3 and holds a component,may be included in the electronic apparatus 1. The holder 28 illustratedin FIGS. 9 and 10 holds a rear imaging unit 8 (that is, the imagingdevice 8 a and the lighting device 8 b), and is mounted on the frontcasing 3 a. The components in the electronic apparatus 1 can beorganized by providing the holder 28 on an area with the componentscollectively arranged therein.

The back casing 3 b is provided so as to face the battery 21. The backcasing 3 b in the first example is integrally molded with a supportingstructure 29. That is, the supporting structure 29 can be a part of theback casing 3 b. Similarly to the plate-like component 26, thesupporting structure 29 is provided for reducing deformation and cracksof the cover panel 2 due to a load from the outside. The supportingstructure 29 extends through the opening 44 and supports the cover panel2. In the present embodiment, an area supported by the supportingstructure 29 in the cover panel 2 is referred to as a “third area 42.”Since the third area 42 is supported by the supporting structure 29, thethird area 42 has resistance to deformation and breakage even when aload is applied from the outside. The supporting structure 29 is madeof, for example, the same material as that of the casing 3.

As shown in FIGS. 9 and 10, the supporting structure 29 is smaller thanthe opening 44 because the supporting structure 29 extends through theopening 44. Therefore, the third area 42 supported by the supportingstructure 29 is inside of the area facing the opening 44 in the coverpanel 2. As illustrated in FIG. 11, the area facing the opening 44 inthe cover panel 2 is inside of the first area 40 supported by the casing3, and is separated from (or adjacent to) the first area 40 and thesecond area 41. Accordingly, the third area 42 is positioned between thefirst area 40 and the second area 41, and is separated from the firstarea 40 and the second area 41. In FIG. 11, the third area 42 isindicated by a striped pattern. An area which is not supported by thefront casing 3 a in the cover panel 2 (that is, an area other than thefirst area 40, the second area 41, and the third area 42 in the coverpanel 2) is referred to as a “fourth area 43.”

In the example of FIGS. 9 and 10, the supporting structure 29 isprovided in the area facing the opening 44 in the back casing 3 b.However, the area with the supporting structure 29 provided therein isnot particularly limited thereto. For example, the supporting structure29 may be provided in the area constituting the side surface of theelectronic apparatus 1 in the casing 3. For example, the supportingstructure 29 can be formed such that the supporting structure 29 extendsto the inside from the inner surface of the area constituting the sidesurface of the electronic apparatus 1 in the casing 3, and can be curvedin the form of a character L toward the opening 44. The supportingstructure 29 in the form of a character L supports the cover panel 2. Inthe casing 3, as illustrated in FIGS. 9 and 10, the cover panel 2 can bemore reliably supported by adopting the supporting structure 29 linearlyextending from the area facing the opening 44, passing through theopening 44, and supporting the cover panel 2, than by adopting thesupporting structure in the form of a character of L.

Front Casing and Plate-Like Component

FIG. 12 is a front view illustrating the front casing 3 a and theplate-like component 26. As described above, the front casing 3 a isintegrally formed with the plate-like component 26. As illustrated inFIG. 12, for example, the plate-like component 26, indicated by obliquelines, is provided in the front casing 3 a. The plate-like component 26has, for example, a substantially rectangular shape in a plan view.

The plate-like component 26 is provided with an opening 44. Asillustrated in FIGS. 9 and 12, the opening 44 is, for example, athrough-hole that penetrates from the first surface 60 to the secondsurface 61. The opening 44 is provided in an area which is intended tobe passed through by the cable 25, an area which may be an interruptionfor the arrangement of an electronic component constituting theelectronic apparatus 1 such as the front imaging unit 4, or an areawhere a metal (which is a material of the plate-like component 26) maybecome an interruption to the properties of the antenna 15.

The opening 44 illustrated in FIG. 12 has a shape in which a rectangularthrough-hole is combined with a circular through-hole. A plurality ofcables 25 pass through the rectangular through-hole as illustrated inFIG. 9. In this manner, the cable 25 can be efficiently wired by wiringthe cable 25 using the opening 44. Further, the front imaging unit 4 isprovided in the circular through-hole. Since the front imaging unit 4is, for example, mounted on the printed board 27 or held by the holder28, the front imaging unit 4 extends through the circular through-holeand is exposed (see FIG. 1) to the front surface of the electronicapparatus 1. The supporting structure 29 may extend through the circularthrough-hole.

The shape, the position, and the size of the opening 44 illustrated inFIG. 12 are merely examples. The opening 44 may be provided asillustrated in FIG. 13. FIG. 13 is a view illustrating the front casing3 a and the plate-like component 26. In FIG. 13, the plate-likecomponent 26 is indicated by oblique lines in the same manner as that ofFIG. 12.

In the plate-like component 26 illustrated in FIG. 13, the opening 44 isa notch. As illustrated in FIG. 13, even in the case where the opening44 is formed of a notch, it is possible for the supporting structure 29to extend through the opening 44 and support the cover panel 2.

In the examples of FIGS. 12 and 13, the opening 44 is formed to be longand narrow in the short-length direction of the plate-like component 26.However, for example, the opening 44 may be formed to be long and narrowin the longitudinal direction of the plate-like component 26. Inaddition, in the examples of FIGS. 12 and 13, the opening 44 is providedin an upper end when the plate-like component 26 is seen in a plan view.However, for example, the opening 44 may be provided on a lower end whenthe plate-like component 26 is seen in a plan view. The shape or theposition of the opening 44 can be appropriately changed according to apurpose of providing the opening 44.

Shape of Supporting Structure

FIG. 14 illustrates an example of the supporting structure 29. Anopening 45 through which the cable 25 passes is provided in thesupporting structure 29. Therefore, the supporting structure 29 does notinterrupt the wiring of the cable 25 when the opening 45 is provided inthe supporting structure 29.

The position, the size, and the shape of the opening 45 are not limitedto the example illustrated in FIG. 14 and can be appropriately changedaccording to the shape of the cable 25 and the position of the cable 25as it passes through the opening 45. For example, as illustrated in FIG.15, the opening 45 may be a notch. In addition, in the supportingstructure 29 illustrated in FIG. 14, only one opening 45 is provided.However, a plurality of openings 45 may be provided in one supportingstructure 29.

In other examples, the cable 25 can be arranged without passing throughthe opening 45 in order to stably support the third area 42 of the coverpanel 2 in view of maintaining the quality of the supporting structure29. In the example of FIG. 9, since the cable 25 connecting the touchpanel 17 with the printed board 27 is arranged so as to pass through thedisplay device 16 and the component 26, the cable 25 does not passthrough the opening 45 provided in the supporting structure 29.Similarly, since the cable 25 connecting the display device 16 with theprinted board 27 is arranged so as to pass through the display device 16and the component 26, the cable 25 does not pass through the opening 45provided in the supporting structure 29. In this manner, in the exampleswhere the cable 25 is arranged so as to pass through the display device16 and the component 26, the opening 45 through which the cable 25passes is not necessarily provided in the supporting structure 29.

As illustrated in FIG. 16, the supporting structure 29 may have aplurality of supporting portions 30 a and 30 b separated from each otherinstead of providing the opening 45 in the supporting structure 29.Hereinafter, when the supporting portions 30 a and 30 b do not have tobe distinguished from each other, they are referred to as supportingportions 30. As illustrated in FIG. 16, a gap 46 is present between thesupporting portions 30 a and 30 b. The cable 25 is arranged by passingthrough the gap 46. In this manner, the supporting structure 29 does notinterrupt the wiring of the cable 25 when the cable 25 passes throughthe gap 46 of the plurality of supporting portions 30 constituting thesupporting structure 29.

The shape and the size of the supporting portions 30 constituting thesupporting structure 29 may be different from each other. In thesupporting structure 29 illustrated in FIG. 16, the supporting portion30 b is larger than the supporting portion 30 a. The supportingstructure 29 illustrated in FIG. 16 has two supporting portions 30.However, the number of the supporting portions 30 constituting thesupporting structure 29 is not limited to two.

Second Example Embodiment

FIG. 17 is a cross-sectional view of an electronic apparatus 1 accordingto a second example embodiment. FIG. 18 is an exploded perspective viewillustrating the electronic apparatus 1 according to the second exampleembodiment. In FIG. 18, similarly to FIG. 10, some of the componentsincluded in the electronic apparatus 1, such as a touch panel 17, areomitted for avoiding complexity in the drawing.

As illustrated in FIGS. 17 and 18, in the second example embodiment, aholder 28 and a supporting structure 29 are integrally formed. A backcasing 3 b and the supporting structure 29 are not integrally formed.The rest of the configuration of the electronic apparatus 1 in thesecond example embodiment is the same as that of the first exampleembodiment.

The holder 28 illustrated in FIGS. 17 and 18 is fixed to a front casing3 a in the same manner as the holder 28 described in the first exampleembodiment. When the electronic apparatus 1 is assembled from the frontcasing 3 a side, the holder 28 is fixed to the front casing 3 a, and thesupporting structure 29 extends through an opening 44. Specifically,when the electronic apparatus 1 illustrated in FIGS. 17 and 18 isassembled from the front casing 3 a side. First, components such as thetouch panel 17, a display device 16, and a piezoelectric vibratingelement 19, which are present on the first surface 60 side of theplate-like component 26, are mounted on a cover panel 2. Subsequently,the front casing 3 a is mounted on the cover panel 2. The holder 28 isfixed to the front casing 3 a. At this time, the supporting structure 29integrally formed with the holder 28 extends through the opening 44 andthe cover panel 2 is supported by the supporting structure 29.

In contrast, for example, when the supporting structure 29 is integrallyformed with the back casing 3 b, and the electronic apparatus 1 isassembled from the front casing 3 a side, all components other than theback casing 3 b are assembled, and then the back casing 3 b is mountedthereon in a final process of assembling the electronic apparatus 1. Inthe process of mounting the back casing 3 b, the supporting structure 29extends through the opening 44.

The holder 28 accommodated in the casing 3 is smaller than the backcasing 3 b. Therefore, when the supporting structure 29 is extendedthrough the opening 44, the opening 44 and the supporting structure 29can be seen at the same time in spite of the presence of the holder 28.Accordingly, the electronic apparatus 1 can be assembled easily.

In the above description, the holder 28 is fixed to the front casing 3a. However, other configurations may be used. For example, the holder 28may be fixed to the back casing 3 b.

Third Example Embodiment

FIG. 19 is a view illustrating a front casing 3 a and a plate-likecomponent 26 according to a third example embodiment. In FIG. 19, theplate-like component 26 is indicated by oblique lines. FIG. 20 is across-sectional view illustrating an electronic apparatus 1 according tothe third example embodiment.

In the front casing 3 a and the plate-like component 26 according tothird example embodiment, an opening 44 is provided in the front casing3 a, and which is different from that of the first example embodiment inwhich the opening 44 is provided in the plate-like component 26. Therest of the configuration of the electronic apparatus 1 in the thirdexample embodiment is the same as that of the first example embodiment.

The plate-like component 26 according to the first example embodimentextends to the side surface supporting the edge area (the first area 40)of the cover panel 2 in the casing 3, but the plate-like component 26according to the third example embodiment does not extend to the sidesurface. The front casing 3 a according to the third example embodimentincludes a projection 800 extending to the inside of the casing 3 fromthe inner surface of the side surface supporting the edge area of thecover panel 2 as illustrated in FIGS. 19 and 20. The projection 800extends to the plate-like component 26 so as to face the cover panel 2.The projection 800 includes a first surface 80 facing the cover panel 2and a second surface 81 on the opposite side to the first surface 80.The opening 44 is a through-hole penetrating into the projection 800from the first surface 80 to the second surface 81.

In this manner, even when the opening 44 is provided in the front casing3 a, the supporting structure 29 can support the cover panel 2 becausethe supporting structure 29 extends through the opening 44 asillustrated in FIG. 20. Therefore, the opening 44 may be provided in thefront casing 3 a.

The opening 44 provided in the front casing 3 a may be a notch providedin the front casing 3 a as illustrated in FIG. 21. FIG. 21 is a viewillustrating the front casing 3 a and the plate-like component 26. InFIG. 21, the plate-like component 26 is indicated by oblique lines inthe same manner as that of FIG. 19. As illustrated in FIG. 21, even whenthe opening 44 is a notch provided in the front casing 3 a, thesupporting structure 29 can support the cover panel 2 because thesupporting structure 29 extends through the opening 44.

The front casing 3 a with the opening 44 provided therein and theplate-like component 26 may be adopted in the second example embodiment.

Fourth Example Embodiment

FIG. 22 is a view illustrating a front casing 3 a and a plate-likecomponent 26 according to a fourth example embodiment. The plate-likecomponent 26 is indicated by oblique lines in FIG. 22. FIG. 23 is across-sectional view illustrating an electronic apparatus 1 according tothe fourth example embodiment.

The plate-like component 26 according to the fourth example embodimentdoes not extend to a side surface supporting the edge area of a coverpanel 2 in a casing 3 in the same manner as that of the third exampleembodiment. The size of the plate-like component 26 is the same as thatof a display device 16 in a plan view. In the cover panel 2, a secondarea 41 faces the plate-like component 26 through the display device 16.A front casing 3 a does not include a projection 800 as does the thirdexample embodiment. An area 47 which does not face both of the frontcasing 3 a and the plate-like component 26 is present in the cover panel2. The rest of the configuration of the electronic apparatus 1 in thefourth example embodiment is the same as that of the first exampleembodiment.

In the fourth example embodiment, a supporting structure 29 supports anarea 47 which does not face both the front casing 3 a and the plate-likecomponent 26 in the cover panel 2. In the cover panel 2, a third area 42supported by the supporting structure 29 is positioned between a firstarea 40 supported by the casing 3 and a second area 41 facing theplate-like component 26 and the display device 16, and is separated fromthe first area 40 and the second area 41.

In this manner, in fourth example embodiment, the cover panel 2 hasresistance to breakage because the cover panel 2 is supported by thesupporting structure 29.

The front casing 3 a and the plate-like component 26 according to thesecond example embodiment of FIG. 17 can be adopted in the fourthexample embodiment.

Fifth Example Embodiment

FIG. 24 is a cross-sectional view of an electronic apparatus 1 accordingto a fifth example embodiment. As illustrated in FIG. 24, a plate-likecomponent 26, a battery 21, and a printed board 27 are disposed from thefront surface side to the rear surface side of the electronic apparatusin this order. That is, the positions of the printed board 27 and thebattery 21 of the electronic apparatus 1 described in the first exampleembodiment, shown in FIG. 9, are switched with each other. The rest ofthe configuration of the electronic apparatus 1 in the fifth exampleembodiment is the same as that of the first example embodiment.

In this manner, even when the positions of the printed board 27 and thebattery 21 are switched with each other, the cover panel 2 can besupported by the supporting structure 29 similarly to that of the firstexample embodiment described above. In addition, in the second exampleembodiment, in the third example embodiment, or in the fourth exampleembodiment, the positions of the printed board 27 and the battery 21 maybe switched with each other.

Sixth Example Embodiment

FIG. 25 is an exploded perspective view of an electronic apparatus 1according to a sixth example embodiment. FIG. 26 is a cross-sectionalview of the electronic apparatus 1 according to the sixth exampleembodiment. FIG. 26 is a cross-sectional view of the electronicapparatus 1 taken along a line B-B illustrated in FIG. 25. Asillustrated in FIGS. 25 and 26, casing 3 is configured of one member andhas a substantially box shape of which one surface is opened.

Since the casing 3 is configured of one member, the electronic apparatus1 is assembled from the rear surface side. More specifically, asillustrated in FIGS. 25 and 26, a battery 21 and a printed board 27 aredisposed on the inner bottom surface of the casing 3. Next, a secondsurface 61 of a plate-like component 26 is disposed so as to face thebattery 21 and the printed board 27. The size of the plate-likecomponent 26 is the same as that of the display device 16 in a plan viewsimilarly to the fourth example embodiment. Next, the display device 16is provided so as to face a first surface 60 of the plate-like component26. A cover panel 2 and a touch panel 17 are provided so as to face thedisplay device 16. A piezoelectric vibrating element 19 is attached tothe cover panel 2. However, the sixth example embodiment is not limitedthereto and a normal dynamic receiver may be included.

The electronic apparatus 1 according to the sixth example embodimentincludes a panel fixing member 31 for fixing the cover panel 2 and thecasing 3. The panel fixing member 31 is fixed to the edge area of thesecond surface 71 of the cover panel 2. The panel fixing member 31 alsois fixed to the side wall of the casing 3. The edge area of the coverpanel 2 is fixed to the casing 3 through the panel fixing member 31 inthe sixth example embodiment.

In the sixth example embodiment, a supporting structure 29 is providedin the casing 3. The supporting structure 29 is fixed to, for example,the inner bottom surface or the inner side surface of the casing 3. Thesupporting structure 29 includes supporting portions 30 c and 30 d. Thesupporting structure 29 extends between an area facing the plate-likecomponent 26 in the casing 3 and the inner side surface of the casing 3,and supports the cover panel 2. In addition, the supporting structure 29may be integrally formed with a holder 28 in the same manner as that ofthe second example embodiment.

FIG. 27 is a view illustrating the cover panel 2 according to the sixthexample embodiment. As shown in FIGS. 26 and 27, first area 40(left-upward oblique line) which is an area of the edge area of thecover panel 2 is supported by the casing 3 through the panel fixingmember 31. A second area 41 (right-upward oblique line) corresponding tothe display device 16 in the cover panel 2 is supported by components inthe casing 3. Further, a third area 42 is present between the first area40 and the second area 41 in the cover panel 2. The third area 42 (thirdarea 42 a and 42 b) is supported by the supporting structure 29. Morespecifically, the third area 42 a is supported by a supporting portion30 c and the third area 42 b is supported by a supporting portion 30 d.In this manner, in sixth example embodiment, since the cover panel 2 issupported by the supporting structure 29, the cover panel 2 hasresistance to breakage.

Moreover, as illustrated in FIGS. 26 and 27, the third area 42 supportedby the supporting structure 29 is separated from an area 90 in which thepiezoelectric vibrating element 19 is disposed in the cover panel 2. Inthis manner, vibration of the cover panel 2 due to the piezoelectricvibrating element 19 is difficult to be reduced because the third area42 supported by the supporting structure 29 is separated from an area 90in which the piezoelectric vibrating element 19 is disposed in the coverpanel 2.

In the above-described embodiment, the supporting structure 29 is fixedto the casing 3 and is described as an example. However, the supportingstructure 29 may be fixed to the cover panel 2. The supporting structure29 may be configured of a plurality of members. FIG. 28 is across-sectional view of the electronic apparatus 1. The supportingstructure 29 illustrated in FIG. 28 is configured of a panel sidesupporting structure 29 a and a casing side supporting structure 29 b.More specifically, the panel side supporting structure 29 a and thecasing side supporting structure 29 b are combined to function as thesupporting structure 29 illustrated in FIG. 26. The panel sidesupporting structure 29 a and the casing side supporting structure 29 bmay or may not be fixed to the same component. For example, the panelside supporting structure 29 a may be fixed to the cover panel 2, andthe casing side supporting structure 29 b may be fixed to the casing 3.

The supporting structure 29 illustrated in FIGS. 29 and 30 may beadopted. FIG. 29 is another example of exploded perspective view of theelectronic apparatus 1. FIG. 30 is a cross-sectional view of theelectronic apparatus 1 taken along a line C-C indicated in FIG. 29. Inthe electronic apparatus 1 illustrated in FIGS. 29 and 30, thesupporting structure 29 and the holder 28 holding a rear imaging unit 8are separately included. Each of the supporting structure 29 and theholder 28 is directly or indirectly fixed to the casing 3. Here,“indirectly” means that each of the supporting structure 29 and theholder 28 is fixed to the casing 3 through another member.

The holder 28 includes a holding portion 28 a holding the rear imagingunit 8 and an extending portion 28 b extending along the inner bottomsurface of the casing 3. The extending portion 28 b is in contact withthe inner bottom surface of the casing 3. On the other hand, thesupporting structure 29 includes a casing facing portion 129 facing theinner bottom surface of the casing 3 and a holder facing portion 130facing the extending portion 28 b of the holder 28.

As illustrated in FIG. 30, the upper end of the cover panel 2 includes athird area 42 c supported by the casing facing portion 129 of thesupporting structure 29, and a third area 42 d supported by the holderfacing portion 130 of the supporting structure 29.

The third area 42 c is stably supported by the casing facing portion 129(supporting portion 30 c) directly extending to the third area 42 c fromthe bottom surface of the casing 3 which faces the third area 42 c.

On the other hand, the third area 42 d is supported by the holder facingportion 130 extending to the third area 42 d from the extending portion28 b of the holder 28 which faces the third area 42 d. As describedabove, the extending portion 28 b of the holder 28 is in contact withthe inner bottom surface of the casing 3. Therefore, the third area 42 dis supported by supporting portions 30 f which are configured of theholder facing portion 130 and the extending portion 28 b which areprovided from the bottom surface of the casing 3 to the third area 42 d.Consequently, the cover panel 2 can be stably supported at the thirdarea 42 d in the same manner as the third area 42 c. That is, even whenthe supporting structure 29 is not provided from the inner bottomsurface of the casing 3 to the cover panel 2, the cover panel 2 can bestably supported when the combination of the supporting structure 29 anda component disposed on the bottom surface of the casing 3 is providedfrom the inner bottom surface of the casing 3 to the cover panel 2. Thesupporting structure 29 and the component may be provided without a gapfrom the inner bottom surface of the casing 3 to the cover panel 2.

Since the extending portion 28 b of the holder 28 is interposed betweenthe supporting structure 29 (holder facing portion 130) and the innerbottom surface of the casing 3, the holder 28 is difficult to be movedin the casing 3. That is, the holder 28 can be securely fixed to thecasing 3 by interposing the extending portion 28 b between thesupporting structure 29 (holder facing portion 130) and the inner bottomsurface of the casing 3.

In the examples of FIGS. 29 and 30, the supporting portions 30 fdirectly extending from the inner bottom surface of the casing 3 to thecover panel 2 are configured of the holder facing portion 130 of thesupporting structure 29 and the extending portion 28 b of the holder 28.However, the supporting portions 30 f may be configured of thesupporting structure 29 and a component other than the holder 28 such asa second component. For example, in an example where a dynamic speakeris adopted instead of the piezoelectric vibrating element 19, thesupporting portions 30 f may be configured of the dynamic speaker andthe supporting structure 29. In addition, the number of components otherthan the supporting structure provided in the casing 3 which constitutesthe supporting portions 30 f may be two or more.

In the examples of FIGS. 29 and 30, the cover panel 2 includes the thirdarea 42 c supported by a supporting portion 30 e (casing facing portion129), and the third area 42 d supported by the supporting portions 30 f(the holder facing portion 130 and the extending portion 28 b). However,the cover panel 2 may include only the third area 42 c supported by thesupporting portion 30 e (casing facing portion 129) or only the thirdarea 42 d supported by the supporting portions 30 f (the holder facingportion 130 and the extending portion 28 b).

In the examples of FIGS. 29 and 30, the supporting structure 29 is fixedto the casing 3, and is described as an example, but the supportingstructure 29 may be fixed to the cover panel 2. The supporting structure29 may be configured of a plurality of components. FIG. 31 is across-sectional view of the electronic apparatus 1 corresponding to FIG.30. The supporting structure illustrated in FIG. 31 is configured of thepanel side supporting structure 29 a and the casing side supportingstructure 29 b in the same manner as the supporting structureillustrated in FIG. 28. More specifically, the panel side supportingstructure 29 a and the casing side supporting structure 29 b arecombined to function as the supporting structure 29 illustrated in FIG.30. The panel side supporting structure 29 a and the casing sidesupporting structure 29 b may or may not be fixed to the same component.For example, the panel side supporting structure 29 a may be fixed tothe cover panel 2 and the casing side supporting structure 29 b may befixed to the casing 3.
